Answer 1

Answer:

0.50

Step-by-step explanation:

Given that a package of self-sticking notepads contains 6 yellow, 6 blue, 6 green, and 6 pink notepads. An experiment consists of randomly selecting one of the notepads and recording its color

The probability that a green notepad is selected given that it is either blue or green is to be found out

Let A = event that selected notepad is green or blue

B = selected notepad is green

The probability that a green notepad is selected given that it is either blue or green is to be found out

= P(B/A)

=P(AB)/P(A)

=Prob (green)/P(green or blue)

= $\frac{\frac{Green}{Total} }{\frac{Green+Blue}{Total} } \\=\frac{6/24}{12/24} \\=0.50$
