The probability of unlocking the door in the second try = (3/4) (1/3) = 1/4. The probability of unlocking the door in the third try = (3/4) (2/3) (1/2) = 1/4. Therefore, the probability of unlocking the door in at most three tries = 1/4 + 1/4 + 1/4 = 3/4. Example 7.3.6 simply tires coupons https://senetentertainment.com
