Question

Below is the probability of three independent events happening. Find the probability that at least one of these events happens. Round your answer to two decimal places. Event 1 : 5/6event 2: 3/8event 3: 6/7

Answer 1

hello

to find the probablity of one of the evet occuring is

$p(1)\times p(2)\times p(3)=\frac{5}{6}\times\frac{3}{8}\times\frac{6}{7}=\frac{15}{56}$

the probablity of at least one of the event occuring is equal to 15/56
