Question

Sean has a bag with 15 marbles. Six of the marbles are red, and 9 are blue. If Sean draws one marble from the bag, the probability of drawing a red marble is___%

Answer 1

Hii frnds.......

Given,

Total marbles = 15

Red marbles = 6

Blue marbles = 9

P(drawing a red marble) = 6 / 15 × 100

in % = 40%

Hope this helps......... :D

Answer 2

Hi,

S= (6R,9B)

n(S)=(15)

E=(R)

n(E)=(6)

P(E)=n(E)/n(S)

P(E)=6/15

%P(E)=6/15*100

=40%

Remember: Multiply the derived P(E) by 100 to get it's percentage!

So the % of getting red ball is 40%

Hope it's helpful
