Answer: In 35 ways Jasmine can draw a blue or yellow marble from the jar


Explanation:

Total marbles in the jar=number of blue marbles+number of yellow marbles=28+7=35.

The number of ways of drawing a blue or yellow marbles is given by


P^n_r=(n!)/((n-r)!)

Here n=35 and r=1

Therefore,
P^(35)_1=(35!)/((35-1)!)=(35!)/(34!)=(35*34!)/(34!)=35

Thus in 35 ways Jasmine can draw a blue or yellow marble from the jar.
