Solve pattern 66 73 13 21 52 _ 10 20
8090 [49]
The answer would be 61. First, if you are trying to figure out the pattern. You must subtract the second number with the first then fourth number with the fifth and so on, you get.

73 minus 66 equals 7.
21 minus 13 equals 8.
XX minus 52 equals x.
20 minus 10 equals 10.

Basing on the pattern of the set of numbers, x will equal 9, To get this you must do 52 and 9 which will equal 61.

On three rolls of a single​ die, you will lose ​$19 if a 3 turns up at least​ once, and you will win ​$5 otherwise. What is the
kondaur [170]

<u>Answer:</u>

-16 cents

<u>Step-by-step explanation:</u>

We are given that on  three rolls of a single​ die, you will lose ​$19 if a 3 turns up at least​ once, and you will win ​$5 otherwise.

We are to find the expected value of the game.

P (at least one 5 in three rolls) = 1 - P (no. of 3 in three) = 1-(\frac{3}{6} )^2 = 0.875

P (other results) = 1 - 0.875 = 0.125

Random game value = -19, +5

Probabilities: 0.875, 0.125

Expected game value (X) = 0.875 × (-19) + 0.125 × (5) = -16 cents

Therefore, every time you play the game, you can expect to lose 16 cents
