5) a) A box write the sample space for the given experiment. contains 13 white cards numbered 1 through 13. One card with a number greater than 6 is chosen. (7,% A ,10.11 .t2.15) b) A group of 15 people are assigned numbers 1 through 15. A person assigned a number of S or less is chosen. 15,,3.1,1 c A dlub at CBC has five members: Jenny, John, Meliss, Limin and Meg Two of them are to be chosen at random to be the club co-chairs.

Explanation / Answer

Solution:

(c) Since CBC has 5 members Jenny , John , Melissa , Limin and Meg

two of them can be chosen in 5C2 = 10 ways

Sample space = ( Jenny , John ) ( Jenny , Melissa ) ( Jenny , Limin ) ( Jenny, Meg) ( John , Melissa) ( John , Limin)

( John , Meg) ( Melissa , Limin) ( Melissa , Meg ) and ( Limin , Meg)

(d) we have to find event B when sum of numbers on both die should be less than 5

there (1,1) (1,2) (1,3) ( 2,1) (2,2) ( 3,1)
