Henry’s Dinner #shorts

[excelmaster]

0, Henry tragically died in the afternoon

[shreeniwaz]

0.8 * 0.15 + 0.2 * 0.95 = 0.31
i.e. there is 31% chance that Henry will have Pasta tonight..

[ZacharyTLawson]

Imagine Henry is having 100 dinners: 80 from the college, 20 from himself. 12 of the college dishes are pasta (80 x 0.15). 19 of his dishes are pasta (20 x 0.95). 12 + 19 = 31/100 dinners are pasta. 31% 😎

Really like this teacher. Please show more of him

[Science_-]

wait, so Henry has a 100 percent probability of eating all the time?!

[curse_devil_]

Henry cooked himself tonight and made Henry-roast with extra chilli sauce 🗿💀

[FrogworfKnight]

Others have already said it, but 31% seems right. (.8*.15+.2*.95)*100=31%

To find the probability that Henry is having pasta for dinner, we can use the law of total probability. Let's denote:
- \( P(C) \) as the probability Henry eats dinner provided by the college, which is 0.8 (or 80%).
- \( P(H) \) as the probability Henry cooks for himself, which is 0.2 (or 20%).
- \( P(P | C) \) as the probability Henry eats pasta given he eats dinner provided by the college, which is 0.15 (or 15%).
- \( P(P | H) \) as the probability Henry eats pasta given he cooks for himself, which is 0.95 (or 95%).

Using the law of total probability, the probability that Henry is having pasta (\( P(P) \)) can be calculated by:
\[ P(P) = P(P | C) \times P(C) + P(P | H) \times P(H) \]
\[ P(P) = (0.15 \times 0.8) + (0.95 \times 0.2) \]
\[ P(P) = 0.12 + 0.19 \]
\[ P(P) = 0.31 \]

Therefore, the probability that Henry is having pasta for dinner is 0.31, or 31%.
I'm indian but intelligence from ur country 🧠

Lower than the chance that my brain will explode.

[jazzman]

That one guy who laughed gets it. Utterly relatable joke. 😂😂😂

[shubhsharma]

There is a 31% probability that he will eat pasta .
80% ×15% +95%×20%

[corona]

If Henry is 95% sure, the he will have pasta 100%

[sophuswong]

tbf this is one of the only probability questions that are accurate

[ashishtiwary]

If I start solving this, Henry will probably die hungry.

[RedRad]

He forgot one very important, real-life parameter: Henry's account balance
For little money, it's just 99% pasta; if he has no more money, it's 30% plain bread and 70% nothing

[IndigoIndustrial]

Just looking at those equations on the big white boards gave me flashback anxiety to undergrad mathematics.

[playmarret]

I wouldn't think here would be so much jokes over this maths Theory of Posibility😂

[aka_krystaI]

Typical jee mains question
Bayes therom 😂

[F.Butler]

He’ll either have pasta or he won’t so it’s 50%

[vrindamadan]

31 percent theorem of total probability
