In an area having sandy soil, 60 small trees of a certain type were planted, and another 60 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 0.7 and the probability of 1-year survival in clay soil is 0.6, compute an approximation to P(-6 SX- YS 6) (do not bother with the continuity correction). (Round your answer to four decimal places.)
