One satellite is scheduled to be launched from cape canaveral in florida, and another launching is scheduled for vandenberg air force base in california. let a denote the event that the vandenberg launch goes off on schedule, and let b represent the event that the cape canaveral launch goes off on schedule. if a and b are independent events with p(a) > p(b), p(a ∪ b) 5 .626, and p(a ∩ b) 5 .144, determine the values of p(a) and p(b) to three decimal places.

Step-by-step explanation:

Given

and we know

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
