A number card is drawn randomly from the set of number from 6 to 40. What is the probability that the card may be prime number or a cube number ? a) 0.4
b)0.47
c) 0.41
d) 0.43

C) 0.41

Step-by-step explanation:

Total number of possible outcomes = 34

Prime numbers from 6 to 40= 13

7,11,13,15,17,19,23,29,31,33,35,37,39

Cube number between 6 to 40 = 1

3x3x3=27

No of prime numbers + cube numbers = 14

Probability

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
