Answer:
1) P(tacos)= 10/30= 1/3
2) P(Pizzas)=18/30 =3/5
3) P(T AND P)= 5/30= 1/6
4) P(T OR P)= P(T) +P(P) - P(T AND P)
= 10/30 +18/30 -5/30
= 23/30
In the 500 spin test, 4 was chosen 121 times. This mean it was chosen 121 times out of 500, or 121/500.
Now, we need to convert this into a percent. We do this by dividing the numerator by the denominator, and multiplying the result by 100.
121/500 * 100 = 24.2, so the probability of spinning a 4 is 24.2%.
