What is the value of the question mark?
Show me how you found the answer

Let success be that a plant dies in the winter and failure be that a plant survives the winter, then
 p = 0.05, q = 1 - 0.05 = 0.95

a.) P(1 or more will not survive the winter) = 1 - P(all will survive the winter) = 1 - P(0) = 1 - 10C0 (0.05)^0 (0.95)^10 = 1 - 1(1)(0.5987) = 0.4013

b.) P(all will survive) = P(none will die) = P(0) = 0.5987
