In the drawing, six out of every ten tickets are winning tickets. Of the winning tickets, one out of every three awards a larger prize.

What is the probability that a randomly chosen ticket will award a larger prize?

A. [tex]\frac{2}{15}[/tex]

B. [tex]\frac{1}{5}[/tex]

C. [tex]\frac{5}{9}[/tex]

D. [tex]\frac{5}{6}[/tex]



Answer :

To determine the probability that a randomly chosen ticket will award a larger prize, let's break down the problem into manageable parts using the given information.

1. Determine the probability of selecting a winning ticket:
We are given that six out of every 10 tickets are winning tickets. Therefore, the probability of selecting a winning ticket (P(W)) is:
[tex]\[ P(\text{Winning}) = \frac{6}{10} = 0.6 \][/tex]

2. Determine the probability that a winning ticket awards a larger prize:
Of the winning tickets, one out of every three awards a larger prize. Hence, the probability of getting a larger prize given that we have a winning ticket (P(Large | Winning)) is:
[tex]\[ P(\text{Large} | \text{Winning}) = \frac{1}{3} \approx 0.333 \][/tex]

3. Calculate the probability of getting a larger prize:
The overall probability that a ticket awards a larger prize (P(Large)) is found by multiplying the probability of selecting a winning ticket by the probability that a winning ticket awards a larger prize:
[tex]\[ P(\text{Large}) = P(\text{Winning}) \times P(\text{Large} | \text{Winning}) = 0.6 \times 0.333 = 0.2 \][/tex]

4. Convert the probability to a fraction:
To match the answer to given options, we express this probability in fraction form. We know:
[tex]\[ 0.2 = \frac{1}{5} \][/tex]

Therefore, the probability that a randomly chosen ticket will award a larger prize is:
[tex]\[ \boxed{\frac{1}{5}} \][/tex]
