Question

Assume that a die is tossed twice and the numbers showing on the top faces are recorded in sequence. Determine the elements in the event given that the sum of the numbers is less than 7.

A.{(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,3), (2,4), (3,1), (3,2), (3,3), (4,1), (4,2), (5,1)}

B.{(1,1), (1,2), (1,3), (1,4), (1,5), (2,1), (2,3), (2,4), (3,1), (3,2), (3,3), (4,1), (4,2), (5,1)}

C.{(1,1), (1,2), (1,3), (1,4), (1,5), (2,1), (2,3), (2,4), (2,3), (3,1), (3,2), (3,3), (4,1), (4,2), (5,1)}

D.{(1,1), (1,2), (1,3), (1,4), (1,5), (2,1), (2,3), (2,4), (3,1), (3,2), (3,3), (3,4), (4,1), (4,2), (5,1)}

Explanation / Answer

all the event are such that sum of the numbers is less than 7

hence all of them are true events for die is tossed twice and sum of numbers is less than 7
