A die is thrown once. Find the probability of getting a number which has at least 2 factors.

Answer 1

Hey friend!!!


Here's ur answer...


===========================



Possible outcomes :
1, 2, 3, 4, 5, 6


Total number of outcomes = 6

Numbers having at least 2 factors are : 2, 3, 4, 5, 6.

Probability of getting such number = 5/6



==============================



Hope it may help you....



Thank you :) :))

Answer 2

Hey there!

Sample space of a die = { 1 , 2 , 3 ,4 , 5 , 6 }

1 has only one factor .
2 ,3,5has two factors .
4 has 3 factors.
6 has 4 factors.

So, { 2 , 3 , 4 , 5 ,6 } have at least 2 factors.

Probability of getting a number which has at least 2 factors = 5/6 .

Hope helped!
