What do the brackets [eg. (10 7)] mean?

(v) Let Y be the number of flights in the sample that

And what mode on the calculator do we use? GRAD or RAD?


(v) Let Y be the number of flights in the sample that all the passengers can be boarded. Then, Y Bin(n = 10, p = 0.60) P(Y7)+P(Y=8) P(Y) = P(Y = 7) + P(Y = 8) + P(Y = 9) + P(Y = 10) = (9) (06) (0.0)+ (1) (0.6* (0.4+(3) (0.6)*(0.4) + (0.6)30 = 0.3823 8 9
