help with statistics

At least one of the answers above is NOT correct. 1 of the questions remains unanswered. 1 point) A certain Statistics professor is currently trying to get rid of a pesky magpie. The bird hassles the squirrels, makes a lot of noise early in the morning, and is just a general nuisance. Armed with a sling-shot, the professor has three sling-shot pellets and therefore has three chances to hit the magpie. Because the magpie will not "sit still', the professor suggests there is a 0.65 probability of hitting the magpie on his first attempt with the sling-shot. If the magpie is not hit on the first shot, the probability of hitting the magpie decreases by 0.05 for every shot thereafter. A random variable X is to count the number of shots the professor takes at the magpie. Complete the probability distribution of X below and use this to find the probability that at least two shots are taken at the magpie. Compute all probabilities to two decimals. . 310.55 P(X = xjo 651 0.60 (use two decimals in your answer)

Explanation / Answer

To calculate P(X>=2)

P(X>=2)

=1-P(X = 1)

= 1-0.65

= 0.35

So, Probability would be 0.35
