Answer:
0.096
Step-by-step explanation:
The bag contains 10 white , 12 blue, 13 red , 7 yellow and 8 green balls.
All the events of drawing a ball will be independent
so selecting one ball white and one red will be
using the multiplication rule of probability we get
P= P(blue)* P(white) + P(white)*P(blue)
as its said to get one blue and one white but does not specify to get which ball at which place
P=
P= = 0.096
It is given the probability that a dancer like ballet is 0.35
So, P(B) = 0.35
It is given the probability that a dancer like tap is 0.45
So, P(T)= 0.45
The probability that he likes both ballet and tap is 0.30
So,
the probability that the dancer likes ballet if we know she likes tap. This is the case of conditional probability.
So,
= 0.666
= 0.67
Therefore, the probability that the dancer likes ballet if we know she likes tap is 0.67.
Option 3 is the correct answer.
