1/4 is equivalent to 5/20
There are 6! = 720 ways of arranging the lamps.
If the leftmost lamp is red, there are 3 choices of lamp in the leftmost position, and the remaining 5 can be placed in any order, so there are 3×5! = 360 ways of arranging the lamps and the leftmost is red.
Hence there is a 360/720 = 1/2 probability that the leftmost lamp is red.
Ignoring lamp color for the moment, the probability of arranging 3 lit lamps and 3 unlit lamps is the same, 1/2.
Since Ryan arranges the lamps randomly by color, then turns 3 of them on randomly, the two events are independent. So
P(leftmost red AND leftmost lit) = P(red) × P(lit) = 1/2² = 1/4
1 feet is 12 inches and there is 6 segments in one feet then in 12 feet there is 72 segments
Answer:
51,958
Step-by-step explanation:
1x1x1x1= 1 5x5x5x5= 625 3x3x3x3=81
1+625= 626
81+2= 83
