Bonjour !!!❤❤❤

Here is your answer__________________ _____________________________

No. of boys = 35

No. of girls = 25

Total no. of students = 35 + 25 = 60


1 student at random is to be the monitor

Therefore,

Probility of a girl to be chosen

No. of girls / No. of students

25 / 60

=> 5 / 12

Answer:

Here is your answer ❤️❤️❤️

Explanation:

Step ( i ) : 1 student at random is to be the monitor

Step ( i ) : 1 student at random is to be the monitorm = 25

Step ( i ) : 1 student at random is to be the monitorm = 25n = 35 + 25 = 60

Step ( i ) : 1 student at random is to be the monitorm = 25n = 35 + 25 = 60P ( i ) = m / n

Step ( i ) : 1 student at random is to be the monitorm = 25n = 35 + 25 = 60P ( i ) = m / n = 25 / 60

Step ( i ) : 1 student at random is to be the monitorm = 25n = 35 + 25 = 60P ( i ) = m / n = 25 / 60

Step ( i ) : 1 student at random is to be the monitorm = 25n = 35 + 25 = 60P ( i ) = m / n = 25 / 60 = 5 / 12
