c and d are mutually exclusive events find p(c or d)

p(c)=4/11 p(d)=6/11
p(c or d)=
round to three decimal places

Since c and d are mutually exclusive events, this means that they cannot both occur at the same time. Therefore, to find the probability of c or d occurring, we can simply add the individual probabilities of c and d.

p(c or d) = p(c) + p(d)
p(c or d) = 4/11 + 6/11
p(c or d) = 10/11

Therefore, the probability of either event c or event d occurring is 10/11 or approximately 0.909 when rounded to three decimal places.
