Answer 2

Answer:

The Probability of getting a green block is 0.1 and the number of white Blocks is 75.

Step-by-step explanation:

(a)P(Green)=1-(0.25+0.45+0.2)

P(Green)=1-0.9

P(Green)=0.1

(b)Let's use the concept of Direct Proportions to solve this problem :

$\frac{x}{0.25}=\frac{60}{0.2}$

$\frac{100x}{25}=\frac{600}{2}$

$x=\frac{600}{2}*\frac{25}{100}$

$x=75$
