Question

in a simultaneous throw of a pair of dice find the probability of getting an even number on first​

Answer 1

Answer:

Step-by-step explanation:

we throw a pair of dice, so we have 6 possible outcomes on the first and 6 on the second

so, total we have 6 x 6 = 36 outcomes,

now

with even outcome on first we have cases as

CASE 1) with 2 on dice 1= 6 cases as from 2,1 ....... to 2,6

CASE 2) with 4 on dice 1= 6 cases as from 4,1 ....... to 4,6

CASE 3) with 6 on dice 1= 6 cases as from 6,1 ....... to 2,6

total favorable outcomes = 6 + 6 + 6 = 18

probability = favorable / total = 18/36 = 1/2
