Given data is:

Class Number of plants

VI 40

VII 48

VIII 42

IX 39

X 40

Total number of classes = 5

1. Probability that more than 40 plants which are planted by a class = (class VII and class VII)/Total number of

classes

= 2/5

2. Probability that 47 plants which are planted by a class = 0/5 = 0 {since no class has planted 47 plants}

1. Probability that more than 40 plants which are planted by a class = (class IX)/Total number of

classes

= 1/5
