प्रश्न
A cricketer scores the following runs in eight innings:
58, 76, 40, 35, 46, 45, 0, 100
Find the mean score.
उत्तर
Runs scored by the cricketer are 58, 76, 40, 35, 46, 45, 0 and 100.
Mean score = `"Total runs scored in all innings"/"Total number of the innings"`
Mean score = `(58 + 76 + 40 + 35 + 46 + 45 + 0 + 100)/8`
= `400/8`
= 50
Therefore, mean score is 50.
