Question

bag contains some red, blue and yellow balls.60% of the balls are red and 20% are blue. If there are total 150 balls then how many yellow balls are there?​

Answer 1

Pre-experiments are the simplest form of research design. In a pre-experiment either a single group or multiple groups are observed subsequent to some agent or treatment presumed to cause change.

Answer 2

Step-by-step explanation:

Total balls = 150

Number of red balls = 60% of 150

= 60/100 * 150

= 90

Number of blue balls = 20% of 150

= 20/100 * 150

= 30

Number of Yellow balls = 150-( 90+30)

= 150 -120

= 30
