How to calculate a probability
Lelu [443]
Probability is calculated by comparing the odds to a certain event occurring to the number of possible events.

P=\frac{possibility-of-an-event-occuring}{number-of-total-outcomes}

For example, take a six-sided dice number 1-6 on each side. The probability of rolling a 4 would be1 in 6 or 1/6. This is because of the six possible outcomes, rolling a 4 is only one of them.

P(4)=1/6

Now take the same dice. The probability of rolling an even number is 3/6. To see why, lets look at the total possible outcomes:

1
2
3
4
5
6

Of the 6 possibilities, 3 are even numbers.

P(even)=3/6 or 1/2

11. x squared - 7x = 0 12. 3x squared - 4x = 20x + 27
Stella [2.4K]
11. x² - 7x = 0
      x(x) - x(7) = 0
      x(x - 7) = 0
      x = 0    or    x - 7 = 0
                           + 7 + 7 
                               x = 7

Solution Set: {0, 7}

12. 3x² - 4x = 20x + 27
           + 4x   + 4x
             3x² = 24x + 27
      3x² - 24x - 27 = 0
      x = -(-24) ± √((-24)² - 4(3)(-27))
                              2(3)
       x = 24 ± √(576 + 324)
                         6
       x = 24 ± √(900)
                     6
       x = 24 ± 30
                 6
       x = 4 ± 5
       x = 4 + 5    or    x = 4 - 5
       x = 9    or    x = -1

Solution Set: {9, -1}

88-55+ 5x-7=180<br> Find the value of x
marshall27 [118]

Answer:

x = 30.8

Step-by-step explanation:

88 - 55 + 5x -7 = 180

33 + 5x -7 = 180

5x -7 = 180 - 33

5x - 7 = 147

5x = 147 +7

5x = 154

x = 154/5

x = 30.8

Hope you got it.
