Question

In the cartoon there are 15 rectangle a cards of which seven are green and rest are white 18?pentagon cards which three are green and rest are white one card is selected and from the cartoon find the probability that selected card is:
1) a pentagon of green colour
2) a rectangle of white colour

Answer 1

Step-by-step explanation:

Probability = $\frac{what,you,want,to,calculate}{Total,no.of,observations}$

Rectangle:

no.of green cards = 7

no.of white cards = 8

green = $\frac{7}{15}$ ( HOW: 7 is what you want to calculate and 15 is the total no.of observations)

white = $\frac{8}{15}$

Pentagon:

no.of green cards = 3

no.of white cards = 15

green = $\frac{3}{18}$

white = $\frac{15}{18}$

Answer to your questions:

1 - $\frac{3}{18}$

2- $\frac{8}{15}$
