Answer:

P(prize)= 2/7

Explanation:

The probability of getting a prize can be found by dividing the number of favorable outcomes by the total number of outcomes.

P (prize) = favorable / total

The favorable outcome is a prize and there are 10 prizes.

P (prize) = 10 / total

There are 10 prizes and 25 blanks. Add 10 and 25.

10 prizes + 25 blanks= 35 total outcomes

P (prize)= 10/35

This fraction can be simplified. Both the numerator and denominator can be evenly divided by 5.

P(prize)= (10/5) / (35/5)

P(prize) = 2 / (35/5)

P(prize)= 2/7

The probability of receiving a prize is 2/7
