Respuesta :

Given t spinners :

The first has the numbers : from 1 to 5

The second has the numbers : from 1 to 3

So, the sum is less than or equal to 3 can get if the two spinners give 1 or 2

So, the probability to get 1 or 2 from the first spinner = 2/5

And the probability to get 1 or 2 from the second spinner = 2/3

So, total probability = 2/5 * 2/3 = 4/15 = 26.66%

She spends the two spinners 500 times

So, the equation will be :

[tex]26.66\%\times500=x[/tex]

Solve for x:

[tex]26.66\%\times500=133.3[/tex]

So, the number of times = 133
