Mr Connors physics class has 86 students classified by academic year and gender as illustrated in the following table Mr Connor randomly chooses one student to class=

Respuesta :

Based on the given table:

No. of Junior students = 10 + 14 = 24

No. of Female Junior students = 14

The probability that he selects a female, given that he chooses randomly from only the junior is determined by the following formula:

[tex]\text{ Probability = }\frac{\text{ No. of Female Junior students}}{\text{ No. of Junior students}}[/tex]

We get,

[tex]\text{ Probability = }\frac{\text{ 14 }}{\text{ 24 }}\text{ = }\frac{\text{ 7 }}{\text{ 12 }}\text{ \lparen simplified\rparen}[/tex]

Therefore, the probability is 7/12.
