A die is thrown 200 times. If the probability of getting an even number is `2/5dot` How many times an odd number is obtained?

Explanation

P(getting an even number)=`2/5`
P(getting an odd number)=`1 - 2/5 =(5-2)/5=3/5`
Probability=`"No. of favorable outcomes" / "Total number of outcomes"`
`3/5="No. of times an odd number is obtained"/200`
`therefore "No. of times an odd number is obtained" = (3/5)xx200`
`=3xx40 = 120`
`therefore` an odd number will be obtained `120` times
