A thumbtack that is tossed can land point up or point down. The probability of a tack landing point up is 0. 2. A simulation was

Burka [1]

Histograms are used to represent data using bars.

The probability that at least 2 thumbtacks land pointing up when 5 thumbtacks are tossed is 0.28

The probability that at least 2 thumbtacks land pointing up when 5 thumbtacks are tossed is calculated using the following complement rule:

$P(x \ge 2) = 1 - P(0) - P(1)$
