Question

There are 870 boys and 800 girls in a school The probability that a boy chosen at random studies Spanish is 2/3

Answer 1

a) 1060, b)

STEP BY STEP Step-by-step explanation:

Since we have given that

Number of boys = 870

Number of girls = 800

Probability that a boy chosen studies Spanish =

Probability that a girl chosen studies Spanish =

So, the number of boys in the school who study Spanish would be

So, the number of girls in the school who study Spanish would be

So, total number of students who study Spanish would be :

b) What is the probability, as a fraction in its simplest form, that a student

chosen at random from the whole school does not study Spanish?

Number of students who do not study Spanish would be:

So, the probability of students who does not study Spanish would be :

Hence, a) 1060, b)
