about 90.4% 20  is the probability that at most one of them recycles.

In statistics, what does a probability mean?

  • The probability serves as a gauge for how likely an event is to occur. It gauges how likely an event is.
  • P(E) = Number of Favorable Outcomes/Number of Total Outcomes is the formula for probability.

P( one) = p ( 1 only ) + p ( 2nd only) + p ( neither)

            = ( 0.31) ( 0.69) + ( 0.69 )( 0.31) + ( 0.69) ( 0.69)

            ≈ 0.9039

So, the probability that at most one of them recycles is about 90.4%.
