A. 0.5
B. 0.4
C. 0.3
D. 0.6

Answer 1

Answer:

Option D

0.6

Step-by-step explanation:

Given that there are 5 colour marbles in a large bag.

The colours are red, orange, yellow, blue and green.

Also given that there are equal amounts of each colour

Let n be the no of marbles of each colour.

Then total no of marbles = 5(n) = 5n

No of red,blue and yellow marbles = n+n+n = 3n

Prob of drawing a red or blue or yellow = P(red)+P(blue)+P(yellow)

= $\frac{n}{5n} +\frac{n}{5n} +\frac{n}{5n} = \frac{3n}{5n}$

= 0.60
