Question

A box has ten slips of paper
labelled 1, 2, 3, 4, 2,3,1,5, 6 and 3
If shikha Picks a slip, find the
probability of her
A) Getling the number 2
B) Getting the number 5
C) Getting the number 3​

Answer 1

Answer:

Four slips marked as 1,2,3,4 are in a box. Two slips are drawn from it one after the other without replacement

The sample space S for the experiment is

S={(1,2),(1,2),(1,4),(2,1),(2,3),(2,4),(3,1),(3,2),(3,4),(4,1),(4,2),(4,3)}

A= number on the first slip is larger than one on the second slip ={(2,1),(3,1),(3,2),(4,1),(4,2),(4,3)}

B= number on the second slip is greater than 2

={(1,3),(2,3),(1,4),(2,4),(3,4),(4,3}

C= sum of the number on the 2 slips is 6 or 7

={(2,4),(3,4),(4,2),(4,3)}

D= number on the second slip is 2 times the number on first slip

={(1,2),(2,4)}

Clearly (A and D)

∴A and D are mutually exclusive events
