There are 870 boys and 800 girls in a school.
The probability that a boy chosen at random studies Spanish is 2/3
The probability that a girl chosen at random studies Spanish is 3/5
a) Work out the number of students in the school who study Spanish.
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?

a) 1060, b)

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)

b mark me branliest thx

step-by-step explanation:

answer: the center is the median and/or mean of the data. the spread is the range of the data. and, the shape describes the type of graph. the four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. good luck
