Question

Table below gives exactly x successes in 6 trials given aprobability of success of 0.785. Suppose the probability of success represents the probabilitythat a randomly selected flight of a regional airline will arriveon time.    x          0              1               2             3              4            5             6 P(x=x)   0.0001    0.0021      0.0198  0.0962    0.2633   0.3845     0.2340 Find the probability that at least 2 flights will arriveon time.

Explanation / Answer

since it says to find the probability of atleast 2 flights,you want p is greater than or equal to 2 flights. soo you add the probability of 2,3,4,5, and 6. then you take the sum and that is the answer.
