    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.
