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

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.
