Question

A box contains 15 red balls, 15 green balls, 15 black balls, 3 silver balls and 2 gold balls.
What is the probability that a person would draw a silver or gold ball from the box?​

Answer 1

Ànswer:- Probability = 1/10

$\mathscr\red{first \: find \: total \: no. \: of \: balls \: } \\ = > 15 + 15 + 15 + 3 + 2 \\ = total \: balls \: = 50 \\ silver + gold \: balls = 5 \\ \mathfrak\green{ \: probablity = \frac{5}{50} } \\ \mathfrak\blue{ probablity \: of \: getting \: } \\ \mathfrak\blue{ silver \: and \: gold \: ball = \frac{1}{10} }$

Thanks.

Answer 2

Step-by-step explanation:

no of balls=>15+15+15+3+2=total balls = 50silver + goldballs = 5

probablity =5/50

probablity of getting silver and gold ball=1/10
