A scientist hopes to launch a weather balloon on one of the next three mornings. For eachโ€‹ morning, there is a 40โ€‹% chance of suitable weather. What is the probability that there will be at least one morning with suitableโ€‹ weather?

SOMEONE PLEASE HELP ME.

Sagot :

Answer:

118/125

Step-by-step explanation:

We can find first the probability that there isnโ€™t suitable weather:

60/100 * 60/100 * 60/100 = 3/5 * 3/5 * 3/5 = 27/125

now we have just to do this operation

125/125 - 27/125 = 118/125
