Each day the school canteen meal can be one of only three things.
The probability that it is pizza is 0.3
The probability that it is curry is 0.42
What is the probability that it is pasta?

Answer 1

Answer:

0.28

Step-by-step explanation:

Let p be the probability of pasta.

Total probability is = 1

Therefore,

0.3 + 0.42 + p = 1

0.72 + p = 1

p = 1 - 0.72

p = 0.28

The probability that it will be pasta is 0.28
