Given Event A, Event B, and Event C. Event A and Event B are mutually exclusive.

B) 0.55

The probability of the complement of Event A ( P( A⁻ ))  = 0.55

Step-by-step explanation:

Explanation:-

 Given  Event A and Event B are mutually exclusive.

  Given data P(A) = 0.45

                     P(B) = 0.35

                     P(C) = 0.25

The probability of the complement of Event A

                   P( A⁻ ) = 1 - P( A)

                              =  1 - 0.45

                              = 0.55

Final answer:-

The probability of the complement of Event A = 0.55

Step-by-step explanation:

Given

PQ = ai + bj + ck , then

| PQ | =

Here PQ = 4i + 3j + 2k , then

| PQ | = = =
