Question

The probability distribution for a game is shown in the table below.

Answer 1

Given:

It is given that

Probability of winning $ 0 = $\frac{3}{10}$

Probability of winning $ 100 = $\frac{1}{5}$

Probability of winning $ 200 = $\frac{1}{10}$

Probability of winning $ 500 = $\frac{2}{5}$

To find the probability of not winning a cash prize.

Explanation:

Not winning cash prize = winning $ 0

So,

Probability of not winning a cash prize

= Probability of winning $ 0

= $\frac{3}{10}$

Therefore,

The probability of not winning a cash prize is $\frac{3}{10}$. Option D.
