Answer 1

We would be looking at the first question all parts here as:

Total Frequency = 34 + 131 + 124 + 71 + 15 = 375

a) The probability here is computed as:

P(All four) = n(All four) / n(Total) = 34 / 375 = 0.0907
Therefore 0.0907 is the required probability here.

b) The probability here is computed as:
P( Two) = 124 / 375 = 0.3307
Therefore 0.3307 is the required probability here.

c) The probability here is computed as:
P(at least 2) = 1 - P(None) - P(one) = 1 - (71 + 15)/375 = 0.7707
Therefore 0.7707 is the required probability here.

d) The probability here is computed as:
P(less than 2) = 1 - P(at least 2) = 1 - 0.7707 = 0.2293

Therefore 0.2293 is the required probability here.
