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


Sagot :

To find the probability that a randomly chosen ticket will award a larger prize, we can proceed as follows:

1. Determine the probability of drawing a winning ticket:
- There are 10 tickets in total, and 6 out of the 10 tickets are winning tickets.
- The probability of drawing a winning ticket is:
[tex]\[ \frac{6}{10} = 0.6 \][/tex]

2. Determine the probability that a winning ticket will award a larger prize:
- Of the winning tickets, 1 out of every 3 tickets is a larger prize ticket.
- The probability that a winning ticket is a larger prize ticket is:
[tex]\[ \frac{1}{3} \][/tex]

3. Calculate the overall probability of drawing a larger prize ticket:
- To find the overall probability, multiply the probability of drawing a winning ticket by the probability of that winning ticket being a larger prize ticket:
[tex]\[ 0.6 \times \frac{1}{3} = 0.2 \][/tex]

Expressing 0.2 as a fraction, we get:
[tex]\[ 0.2 = \frac{2}{10} = \frac{1}{5} \][/tex]

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