Question
jasmine rolls a number cube 72 times. the number 2 is rolled 13 times and the number 3 is rolled nine times. to the nearest whole percent, what is the experimental probability of rolling a 2 or 3?
7%
18%
22%
31%
Step1: Calcular el número de éxitos
Sumamos los lanzamientos de 2 y 3: $13 + 9=22$.
Step2: Calcular la probabilidad experimental
Dividimos el número de éxitos entre el número total de lanzamientos y multiplicamos por 100: $\frac{22}{72}\times100=\frac{2200}{72}\approx30.56$.
Step3: Redondear al porcentaje entero más cercano
$30.56\approx31\%$.
