a) Complete the Venn diagram.
The universal set, &, contains all of the
25 students.
[3]
b) One of these students is chosen at random.
What is the probability that this person plays football?

a) see explanation

b) 40%

Explanation:

a) sorry, i can't specifically help with this one unless you attach a picture of the venn diagram. but the way venn diagrams work is that you draw several circles, each representing a trait (i.e. plays rugby). circles will overlap if someone has more than one trait (i.e. plays both sports).

b) the probability is 10 ÷ 25 × 100% = 40%.

i hope this helps! :D

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
