41.

A group of students measured a certain angle
(to the nearest degree) and obtained the following
results: 75o, 76o, 72o, 73o, 74o, 79o, 72o, 72o, 77o,
72o, 71o, 70o, 78o, 7

A. 79o

B. 78o

C. 74o

Table:
The table above shows the scores of 15 students in a Physics test.How many students scored at least 5?

A. 1

B. 6

C. 8

D. 9

E. 14

Detailed Solution

No of students that scored at least 5 = 1 + 6 + 1 + 0 + 1 + 0
= 9 students.
43.

A number is chosen at random from the set (1 ,2,3
....,9, 10). What is the probability that the number
is greater than or equal to 7?

A. 1/10

B. 3/10

C. 2/5

D. 3/5

E. 7/10

Detailed Solution

The given set {1, 2, 3, 4 ...., 9, 10}
(x ≥ 7 ) = 7 7, 8, 9, 10 = 4
Total number of possible outcome = 10
4/10 = 2/5
44.

Three balls are drawn one after the other with replacement, from a bag containing 5 red, 9white and 4 blue identical balls, What is the probability that they are one red, one white and one blue?

A. 5/102

B. 5/136

C. 5/162

D. 5/204

E. 5/243

Detailed Solution

Total number of balls = 18
P(1R, 1W, 1B) = 5/18 x 9/18 x 4/18 = 5/162
