Answer:

a) 2/5

b) 1/10

Explanation:

There are 20 people total.

a is that the chosen child is a girl.

2 + 6 = 8, --> there are 8 girls --> simplify

8/20 = 4/10 = 2/5

b is the probability that the chosen child is a left-handed girl, --> there are 2 left-handed girls --> 2/20 --> simplify to 1/10

And thus, we have our answers.

Answer:

A) 2/5

B) 1/10

Explanation:

A) Total Girls = 8

Total Children = 19

Probability =
(NumberOfFavourableOutcomes)/(Total No.OfOutcomes)

Probability = 8/20 = 4/10 = 2/5

B) Left-handed girls = 2

Total left handed children = 20

=> Probability =
(NumberOfFavourableOutcomes)/(Total No.OfOutcomes)

=> Probability = 1/10
