Question

There's a 40% chance of rain on Tuesday and a 50% chance of rain Friday. What percent will it rain both Tuesday and Friday?

p.s. this is a probability question I think

Answer 1

40% or 40/100 which is in decimal format 0.4.

50% or 50/100 which is in decimal format 0.5.

P( tueday AND friday) <----- AND is a keyword, means product

P(tuesday) AND P(friday)

0.4 * 0.5

0.2 or 0.2 * 100 or 20% chance that it will rain on both days.
