Q:

Two dice are tossed. The probability that the total score is a prime number is:

A) 5/12 B) 1/6
C) 1/2 D) 7/9
 
Answer & Explanation Answer: A) 5/12

Explanation:

Clearly, n(S) = (6 x 6) = 36.

Let E = Event that the sum is a prime number.

Then E= { (1, 1), (1, 2), (1, 4), (1, 6), (2, 1), (2, 3), (2, 5), (3, 2), (3, 4), (4, 1), (4,3),(5, 2), (5, 6), (6, 1), (6, 5) }

n(E) = 15.

P(E) = n(E)/n(S) = 15/36 = 5/12.

Q:

In a 100 m race, A beats B by 10 m and C by 13 m. In a race of 180 m, B will beat C by:

A) 5.4m B) 4.5m
C) 5m D) 6m
 
Answer & Explanation Answer: D) 6m

Explanation:

A : B = 100 : 90.

 

A : C = 100 : 87.

 

B/C = (B/A*A/C) = (90/100*100/87) = 30/29

 

When B runs 30 m, C runs 29 m.

 

When B runs 180 m, C runs (29/30*180)m =174m

 

 B beats C by (180 - 174) m = 6 m.
