Considering the given discrete probability distribution, it is found that there is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.
What is the discrete probability distribution?
Researching on the internet, it is found that the discrete probability distribution for the number of packs that Hugo buys is given by:
- P(X = 1) = 0.2.
- P(X = 2) = 0.16.
- P(X = 3) = 0.128.
- P(X = 4) = 0.512.
The probability that he buys fewer than 3 packs is given by:
P(X < 3) = P(X = 1) + P(X = 2).
Hence:
P(X < 3) = P(X = 1) + P(X = 2) = 0.2 + 0.16 = 0.36.
There is a 0.36 = 36% probability that Hugo buys fewer than 3 packs.
