Answer
Question.CO3
total frequency = 9831+7845+6869+6323+5410+5279 =41557
the probability of being in age group 40-49 and 50-59 ={[ 6869/41557]}+{[6323/41557]}=0.1653(approx)+0.152152 (approx.)
=0.3174
0.3174×100= 31.74%
Question.No.22
Classical Probability
Question.No.23
Total frequency = 983 + 784 + 686 + 632 + 541 + 527 = 4153
Hence,
Probability of P(over 60)
= 5410/41557 +5279/41557
= 0.2572
