 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the probability of randomly picking a number from 1 to 10 that is even and randomly picking a number from 1 to 10 that is odd?
 A 1/4 B 2/5 C 2/7 D 1/3
Explanation:

Detailed explanation-1: -we get probability of (a) is equal to 4/10. there are 5 even numbers (2, 4, 6, 8, 10), so the probability of choosing an even number is 5/10. we get probability of (b) is equal to 5/10.

Detailed explanation-2: -To Find, The probability of selecting an odd number. Total outcomes = 10. Hence, the probability of getting an odd number is 1/2.

Detailed explanation-3: -So, probability of the event that a number chosen from 1 to 100 is a prime number =10025=41.

Detailed explanation-4: -Step-by-step explanation: We need to find the probability of the event that a number chosen from the numbers 1 to 10 is divisible by the number 5. So the sample space contains the numbers, The numbers which are divisible by 5 from these are 5 and 10. The probability of the event is 0.2 .
