1. Given:–

   • No. of boys = 15
   • No. of girls = 15

   To Find:–

   • Probability of that she will select a girl ,P(E) ?

   Solution:–

   It is given that the number of boys & girls.

   So , the total number of boys & girls in 8th period =30

   According to the Question

   Total Possible Outcomes = 30

   No. of Favourable Outcomes = 15

   ☯ P(E) = Favourable Outcomes/Total Possible Outcomes

   substitute the value we get

   [tex]\longrightarrow[/tex] P(E) = 15/30

   [tex]\longrightarrow[/tex] P(E) = 1/2

   • Hence, the probability that she will select a girl is 1/2.

2. Given :-

   There are 15 boys and 15 girls in 8th period. If Sean randomly selects a member of 8th period

   To Find :-

   Probability that she will select a girl?

   Solution :-

   We know that

   Probability = Favorable outcomes/Total No. of outcomes

   Probability = 15/30

   Probability = 5/10

   Probability = 1/2
