​

Answer 1

Answer:

Total no. Of outcomes = 25 + 5 =30

So, probability of getting a gift coupon = 5/30

= 1/6

Answer 2

Given - Number of gift and blank coupons

Find - Probability of getting gift coupon

Solution - Probability = number of favourable outcomes/total number of outcomes

Number of favourable outcomes = 5

Total number of outcomes = 5 + 25

Total number of outcomes = 30

Probability = $\frac{5}{30}$

Probability = $\frac{1}{6}$

Probability = 0.17

Therefore, probability of getting a gift coupon is 0.17.
