Your Answer is - C) 0. 27
•Explanation -
Given that -
Total number of Drawing pin , = 100
In which 73 land up
so ,
Number of pins Which would land down = 100 - 73
= 27
So here we need to find The probability of landed down pins , n = 27
so ,
Hence the probability of landed down pins is = 0.27
Hope this would help you !!
