Each of 500 soldiers in an army company independently has a certain disease with probability 1/103. this disease will show up in
a blood test, and to facilitate matters, blood samples from all 500 soldiers are pooled and tested. (a) what is the (approximate) probability that the blood test will be positive (that is, at least one person has the disease)
<span>The chance of the individual has the disease is 1/103, which means there is 102/103 chance to be healthy. The chance of "at </span><span>least one person has the disease" is the opposite of the chance of "everyone healthy".
The chance that all 500 soldiers healthy would be: (102/ 103)^500= </span><span>0.00761155742 </span><span> The chance of </span>at least one person has the disease would be: 1- (102^500/ 103^500)= <span>0.99238844257 = 99.24%</span>
He could race multiple cars with different weight added on them and do multiple races (just to be sure) and see if his theory was correct, if not he should right down what he has learned from his experience! :D
The answer is 100% <span>There are only heterozygous in roses red flowers there offsprings have long stems and the are very dominent </span><span> all of the offspring will have red long stemmed flowers. </span>this one is the right answer hope it helps
