Starting at a fixed time, each car entering an intersection is observed to see whether it turns left (L), right (R), or goes straight ahead (A). The experiment terminates as soon as a car is observed to turn left. Let of cars observed. What are possible X values? List five outcomes and their associated X…

A box contains six 40-W bulbs, five 60-W bulbs, and four 75-W bulbs. If bulbs are selected one by one in random order, what is the probability that at least two bulbs must be selected to obtain one that is rated 75 W?
Answer:- Given: The number of bulbs = The number of bulbs = The number of bulbs = To find: P (At least bulbs must be selected to obtain one that is rated 75w) Step-by-step explanation: Let us reflect as At least bulbs must be certain to obtain one that is rated 75w A1= Just…
