The probability that both students are girls is 0.28
Probability is the likelihood or chance that an event will occur
Probability = n(E)/n(S)
where:
- n(E) is the number of events
- n(S) is the total sample space:
If Mrs. Chavis's statistics class has 26 students in it, then n(S) = 26
Since three are 14 girls in it, hence n(E) = 14
Pr(both students are girls) = 14/26 * 13/25 (without replacement)
Pr(both students are girls) = 182/650
Pr(both students are girls) = 0.28
Hence the probability that both students are girls is 0.28
