Question

Tomiko has a bag that contains several different types of apples. She reaches in the bag, randomly pulls out an apple, records the type in a table, and then places it back in the bag. Her results are shown in the table below.

Type Frequency
Red Delicious 11
Golden Delicious 6
Granny Smith 20
Fuji: 3
Gala 10
Using the results from the table, determine the probability of Tomiko selecting a Granny Smith apple and plot that value on the number line.

Tomiko opens the bag up and discovers there are 4 Granny Smith apples, 1 Golden Delicious apple, 1 Fuji apple, 2 Red Delicious apples, and 2 Gala apples. Use these findings to calculate the probability of randomly picking a Gala apple from the bag. Plot this value on the number line.

We can calculate the probability of selecting a Granny Smith apple by dividing the frequency of Granny Smith apples by the total number of apples:

P(Granny Smith) = 20/(11+6+20+3+10) = 20/50 = 2/5 = 0.4

Plotting 0.4 on the number line:

---0---------------0.4-----------1---

Next, we can calculate the probability of selecting a Gala apple by dividing the frequency of Gala apples by the total number of apples:

P(Gala) = 2/(4+1+1+2+2) = 2/10 = 1/5 = 0.2

Plotting 0.2 on the number line:

---0---------------0.2-----------1---
