The answer is option d) T(Q+6.5) = R
Remember that, for independent events, the probability that both occurr is the product of the individual probabilities.
a) Probability of being contacted: 78% = 0.78
Probaility of refusing: 1 - 22% = 1 -0.22 = 0.78
Combined probability: 0.78*0.78 = 0.6084
b) The probability of failing to contact or making contact and not geeting them to agree 1 - the probability of contacting and getting them to agree.
The probabilityof contacting and getting them to agree is 0.78*0.22 = 0.1716
The the answer to this question is 1 - 0.1716 = 0.8284
Addition bc. you need adding to both sides x and will get this result of 3x+2 = 11
hope helped
It is 54 for 1 and 2 is 2520 you multply the lenght by the whith and divide by 2
