hi can you help me with this question ,,, kinda desperate rn
Answers
Total numbers between 2 and 101= 100
P(E) = Number of favourable outcomes÷Total number of outcomes
a) Number of even numbers = 50 {100/2=50}
P(even number) = 50/100 = 1/2 = 0.5
b) Number of perfect squares between these numbers = 9
P(Perfect square)= 9/100= 0.09
c) Prime numbers less than 20= 10
P(Prime number less than 20)= 10/100 = 1/10 = 0.1
HOPE THIS HELPS!!
Step-by-step explanation:
Total number of results = 100
(2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101)
Even numbers = 50
(2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 76, 78, 80, 82, 84, 86, 88, 90, 92, 94, 96, 98, 100)
Probability = 50/100 = 1/2
Perfect squares = 9
(4, 9, 16, 25, 36, 49, 64, 81, 100)
Probability = 9/100
Prime number less than 20 = 8
(2, 3, 5, 7, 11, 13, 17, 19)
Probability = 8/100 = 4/50 = 2/25
