less
Find the probability of getting number 1, 4 or 5 on a die when a
thrown.
Suppose we throw a dice once (1) What is the probability og
number greater than 3? (2) What is the probability of getting a num
than or equal to 3?
A dice is thrown once. Find the probability of getting (i) a prime number
a number lying between 2 and 5 and (iii) an even number.
Two fair dice are rolled simultaneously. Find the probability of the following
events :

Answer 1

Answer:

Step-by-step explanation:

A dice have 1 to 6 numbers

Probability of getting number 1, 4 or 5 on a die when a  dice thrown = 3/6 = 1/2

Probability of number greater than 3   means ( 4 , 5 , 6)  = 3/6 = 1/2

Probability of getting a num  less than or equal to 3 ( 1 , 2 , 3)  = 3/6 = 1/2

Probability of getting a num  greater than or equal to 3 ( 3 , 4 , 5 , 6)  = 4/6 = 2/3

probability of getting a prime number  a number lying between 2 and 5  i.e 3  = 1/6

probability of getting even number (2 , 4 , 6)  = 3/6 = 1/2

getting the same number on both dice = 1/36
