On your first spin the chance is 1/2. The same goes for your second spin, but the chance of getting two consecutive even numbers is 1/2 x 1/2.
So the answer is 1/4.
Answer:
imagine the upper triangle as the same as the lower one, but rotated by 180° around the corner point they share, and resized.
the base of the smaller triangle is resized by a factor of 3/4.5, or reduced: 1/1.5
we just take the length from the hypotenuse of the bigger triangle and resize it to, either by multiplying with 1/1.5 or by dividing by 1.5
personally, I find the latter easier.
x = 7.5/1.5 = 5
Arrives in Leeds at 11:50 am
Distance = speed x time
Rearrange the formula
Time = Distance/speed
D = 210 miles; S = 90
Time = 210/90 = 2.33 hours
First add 2 hr and then add 0.33333 hr
9:30 + 2 hr = 11:30
Converting 0.33333 into min
0.33 x 60 = 20 min
11:30 + 20 min = 11:50 am
answer: lcd is 24 bc you have to do 12*2 and 8*3
