Question

Use the table to find the experimental probability of spinning a number less than 2. Write your answer as a fraction.

Answer 1

Answer:

The experimental probability of spinning a number less than 2

P( x<2) = 0.14

Step-by-step explanation:

Given data table

x                        7           10            8                8           8            9      = total 50

P(X=x)    $\frac{7}{50} = 0.14$     $\frac{10}{50} = 0.2$  $\frac{8}{50} = 0.16$   $\frac{8}{50} = 0.16$  $\frac{8}{50} = 0.16$   $\frac{9}{50} = 0.18$  

Sum of the probabilities is equal ∑x P(x=x)

                                 = 0.14 +0.2 +0.16 +0.16+0.16 +0.18

                                 =1

Given data table

spinning

a spinner             1            2            3                4           5             6                    

x                        7             10            8                8           8            9      

P(X=x)            0.14     0.2         0.16             0.16         0.16        0.18    

The experimental probability of spinning a number less than 2

P( x<2) = P( x=0) +P(x=1)

          = 0 + 0.14

The experimental probability of spinning a number less than 2

P( x<2) = 0.14
