radioactive source

A radioactive source is observed during 7 time intervals, each interval being 10 seconds in duration. The number of particles emitted during each period is counted. Suppose that the number of particles emitted, say X, during each observed period has an average rate of 0.5 particles per second.

(a) What is the probability that 4 or more particles are emitted in each interval?

(b) What is the probability that in at least 1 of 7 time intervals, 4 or more particles are emitted?
