Estimate the probability of the event. 4) Of 1232 people who came into a blood bank to give blood, 397 people had high blood pressure. Estimate the probability that the next person who comes in to give blood will have high blood pressure. A) 0.241 B) 0.29 C) 0.373 D) 0.322 From the information provided, create the sample space of possible outcomes. 5) Friskie is having her fifth litter. The prior litters have either been three normal pups or two normal pups and a runt. Assume the probability of either outcome is 50%. NNN RNN NR N NN NR NNN NRN C) NNR NNN D) NR NNR NNR Find the indicated complement. Find P(bar A), given that P(A) = 0.493. A) 0.507 B) 0 C) 1.493 D) 2.028

Solution

4) total no. of persons =1232

persons have high blood pressure=397

then required probability =397/1232 =0.322

5)C

6)P(A)=0.493

so

P(A^c ) =1-P(A)=1-0.493=0.507
