In an area having sandy soil, 50 small trees of a certain type were planted, and another 50 trees were planted in an area having clay soil. Let X = the number of trees planted in sandy soil that survive 1 year and Y = the number of trees planted in clay soil that survive 1 year. If the probability that a tree planted in sandy soil will survive 1 year is .7 and the probability of 1-year survival in clay soil is .6, compute an approximation to P(-5 X - Y 5) (do not bother with the continuity correction). and with the other parameter equal to a1 + a2. Is X + Y gamma distributed if the scale parameters are different? Explain.
