Well. U have 6 lamps and we r turning in 3 and the probability of 1 being red is 16.666% u would do 1/6 as a percentage because I are only trying to find if that one is red. Hope this helps! ☺️
Answer:
The answer is 7/20 :)
Step-by-step explanation:
P(leftmost lamp = red) = ½
Leftmost must be red (1/2) and so must the leftmost lit lamp(2/5)
(1/2)(1/2) + (1/2)(1/2)(2/5) = 7/20 :)
