2.1 If an event has a probability that is greater than 0.4, what does it mean? 2.2 What is meant when two events are said to be mutually exclusive?

Step-by-step explanation:

1) i think for the first question any probability greater than 0.4 has more likelihood that it will happen

2) mutually exclusive events are ones that cannot occur at the same time as it's impossible e.g. a single coin toss cannot result in you getting heads and tails

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
