Question

The probability that it rains in London on any particular day is 0.4.
If it rains then the probability of it raining the following day decreases to 0.25.
Consider the next two days.
What is the probability it doesn’t rain on either day?

The probability that it rains today= 0.08
The probability that it doesn’t rain todays= 0.16

### What is probability?

Probability is simply how likely something is to happen. Whenever we’re unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.
The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
Given:
probability that it rains in London on any particular day is 0.4.
probability of it raining the following day decreases to 0.25.
For next two days
The probability that it rains today= 0.2 * 0.4 = 0.08
The probability that it doesn’t rain todays= 0.4*0.4 = 0.16
