in tossing a pair of die,the probability of getting an odd no. or a no. less than 4is

here, total no. of outcomes = 6
outcomes with odd no. or less than 4 = 1, 2, 3, 5

So, P(E) = 4/6 or 2/3

Unbiased die has number of outcomes as 1, 2, 3, 4, 5 and 6.
Probability of getting a odd no. or no. less than 4 = ?
Favourable outcomes are : 
Getting a odd no. = 1, 3, 5
Number less than 4 = 1, 2, 3
P (E) = 3/6
P (E) = 1/2
The probability of getting an odd number or number less than 4 is 1/2.

sample space=1&3
Therefore the probability of getting odd no. &no.less than 4=2/6=1/3
  • 0
Odd no :1,3,5 No less than 4: 1,2,3 Probability= 3/6 =1/2
