A negative even integer x is randomly chosen from the negative integers greater than or equal to -20.
What is the probability that 2x + 10 >-10 ?

Which one ? is the answer and how to find this answer

Afootball quarterback has two more chances to throw a touchdown before his team is forced to punt the ball. he misses the receiver on the first throw 25% of the time. when his first throw is incomplete, he misses the receiver on the second throw 15% of the time. what is the probability of not throwing the ball to a receiver on either throw?

Use a standard normal table to determine the probability. give your answer as a decimal to four decimal places. −1.5< < 1.5)
