Biologists estimate that a randomly selected baby elk has a 44% chance of surviving to adulthood. Assume this estimate is
correct. Suppose researchers choose 7 baby elk at random to monitor. Let X = the number that survive to adulthood.
What is the probability that more than 4 elk in the sample to survive to adulthood?
O 0.6294
O 0.2304
0.8598
0.1402
O 0.3706

p = probability of success = 0.44q = 1 - p = 1 - 0.44 = 0.56 n = number of trials = 7
is the number of different combinations of x objects from a set of n elements, given by the following formula.
. So
