Question

There are 36 balls in a bag.5 of the balls in the bag are red, 10 are blue,5 are green and the rest are white.I pick one ball and it is white. I place that ball on the table and I pick another ball at random.Find the probability that the next ball I pick would be red in colour?

Answer 1

Answer:

1/7

Step-by-step explanation:

total number of balls=36

number of red balls=5

number of blue balls=10

number of green balls,=5

number of white balls=16

after picking white ball ->

total number of balls=35

therefore the probability of a red ball will be

=(number of red balls)/ total number of balls

= 5/35

=1/7
