Question

a box contains 150 oranges.if one orange is taken out from the box at random and the probability of itd being rotten is 0.06 then find the numbof good oranges in the box.

Answer 1

9 is the best answer

Answer 2

Let the probability of good oranges be x

Now know that 1-0.06 =0.94

Now 0.94 comes the probability of good oranges ..

Also the probablity of good oranges is x/150

Now equating these both probability we will get our ans

X/150=0.94
X= 141
