Samuel rolls a fair dice 100 times. How many times will he get a 1 or a 5?
timama [110]
Out of 6, the chance for a 1 or a 5 is 2. Probability is the something is the number of desired outcomes over the number of all possible outcomes. Therefore the probability is 2/6 to roll a 1 or a 5. From here, we need to find how much 2/6 of 100 is.
2/6 = x/100

200/6 = x
33.3 = x
Since its impossible to roll part of a dice, we'll round to a whole number. 33.3 rounds to 33, therefore he will roll a 1 or a 5 33 times.

PLEASE HELP ME!!!!<br><br> (if you don’t know don’t answer)
Sergio039 [100]

Answer:

Here are my answers

hope this helps

Step-by-step explanation:

1. isosceles triangle

2.   3x + 15 = 90       x = 25

     x + 25 = 90        x = 65

     x + 55 = 90        x = 35

3. The size for DAB is 84

My reasoning is I went from one angle to another by subtracting 180 from my answers. For example angle 132 is supplementary to the missing angle next to it. I subtract 180 from 132 and get 48. That already solves the 2 equivalent angles in the triangle so I have 48+48+x = 180 because a full triangle equals 180. I get x = 84 then I do the same thing I did with angle 132. Angle 84 is supplementary to the missing angle next to it. I subtract 84 from 180 and get 96 then go diagonal from angle C (which is 96) to angle A. Those are supplementary so I subtract 96 from 180 and get 84.
