Mathematics: A group of friends are playing a game in which they roll a 4-sided pyramid and pull a marble from a bag of 4 marbles. The faces of the pyramid are the same size and numbered 1 to 4. Each marble is a different color. The colors are green, blue, orange, and purple. The friend that rolls the number 3 on the pyramid and pulls a blue marble wins a point. The results from the first 12 turns are listed: 4 and blue 1 and blue 3 and orange 2 and green 3 and blue 2 and purple 2 and purple 1 and purple 4 and

Theoretical Probability of picking a blue Marble and Rolling a 3 $=\frac{1}{16}$ Experimental Probability of picking a blue Marble and Rolling a 3 $=\frac{1}{12}$

Step-by-step explanation:

If the friends roll a 4-sided pyramid and pull a marble from a bag of 4 marbles.

THEORETICAL PROBABILITY

P(Picking a blue Marble) $=\frac{1}{4}$

P(Rolling a 3) $=\frac{1}{4}$

P(Picking a blue Marble and Rolling a 3) $=\frac{1}{4} X \frac{1}{4}=\frac{1}{16}$

EXPERIMENTAL PROBABILITY

The outcomes from the first 12 turns are:

4 and blue 1 and blue 3 and orange 2 and green 3 and blue 2 and purple 2 and purple 1 and purple 4 and blue 1 and green 4 and orange 3 and green

n(3 and blue)=1

P(Picking a blue Marble and Rolling a 3) $=\frac{1}{12}$

Mathematics

The number of buttons in tin C is 17.
x+4x+x-7= 137
combine like terms
6x-7=137
isolate the variable by adding 7 to both sides
6x=144
divide
x=24
but remember, tin c is x-7 so plug the 24 in, and the answer is 17.
