Answer 1

Step-by-step explanation:

total cards n=100

Que. (a)

*odd numbers in 1 to 100 = 100/2 =50

1,3,5,7,9,11,...99

*two digit odd no =50-5 =45

11,13,15,17,19,...99

p(a) = p/n = 45/100 = 0.45

Que. (b)

*multiple of 11 in 1 to 100 =9

11,22,33,..99

p(b) = 9/100 = 0.09

Que. (c)

*odd no. in 70 to 100 =30/2 =15

71,73,75,77,79,...99

p(c) = 15/100 = 0.15

Que. (d)

*square no. in 1 to 100 =10

1,4,9,16,25,36,49,64,81,100

p(d) = 10/100 = 0.1

Que. (e)

*odd no. in 1 to 100 =50

1,3,5,7,9,...99

*multiple of 7 in 1 to 100 =14

7,14,21,28,35,42,49,56,63,70,77,84,91,98

*odd no. in 1 to 100 but, not multiple of 7 = 50-14 = 36

p(e) = 36/100 = 0.36
