Tim rolls a number cube labeled 1 through 6 and flips a coin. Which is the probability that Tim rolls a number greater than 3 and flips tails?

There are 3 numbers on the cube greater than 3 ( 4, 5, & 6)

This means he has a 3/6 = 1/2 chance of doing that.

He has a 1/2 chance of getting tails on the coin.

The probability of doing both would be the probability of the cube roll x the probability of the coin toss:

1/2 x 1/2= 1/4

The answer is 1/4

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
