Question

A bag contains 3 red balls, 5 yellow balls and 7 pink balls. If one ball is drawn at random from the bag, what is the probability that it is either pink or red?

Answer 1

Answer:Total balls = 3+5+7=15

Favourable outcome =7+3=10

Probability = favourable outcome÷ total no. of outcomes

=10÷15

=2÷3

Step-by-step explanation:

Answer 2

At first,
Number of red balls=3
Number of pink balls=7
Hence,
No. of outcomes=10=3+7
therefore,
probability =no. of outcomes/total no. of of possible outcomes
that is,
10/15=2/3.
hence, probability is 2/3
