A forest has 128 snakes, some venomous and some non-venomous. If a snake is caught at random, the probability that it is venomous is \(\frac{3}{16}\). How many non-venomous snakes are there in the forest?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 104
Probability \(=\) favourable outcomes ÷ total outcomes, so the number of venomous snakes is the probability times the total.
Venomous snakes \(\displaystyle =\frac{3}{16}\times128=24\)
Non-venomous snakes \(=128-24=104\)
