Question

what is the probability that a student will be in both chemistry and math but not Spanish round to three decimal places

Answer 1

3/13

Explanation :

The probablity of an event = favourable outcome / total outcomes

Now in our case,

favorable outcome = 60

Total number of outcomes = 5 + 70 + 5 + 85 + 60 + 15 + 3 + 17 = 260

Therefore,

probablity = 60 / 260

= 3 /13
