You have two sticks. each stick has one blue side and one pink side. you throw the sticks 10 times and record the results. use the table to find the experimental probability of the event.
1. tossing 2 pink
2. tossing 1 blue and 1 pink
3. not tossing all pink
outcome | frecuency
2 blue | 1

Answer:

  • 1. 30%, 2. 60%, 3. 70%

Step-by-step explanation:

According to table the total frequencies is:

  • 1 + 3 + 6 = 10

Probability = Favorable outcome frequency / total frequency

Find each probability according to equation above:

  • 1. P(2 pink) = 3/10 = 30%

  • 2. P(blue and pink) = 6/10 = 60%

  • 3. P(not all pink) = (10 - 3)/10 = 7/10 = 70%

The experimental probability of the event are: 3/10; 3/5; 7/10.

Experimental probability

Frequencies=1 + 3 + 6

Frequencies = 10

Hence:

Tossing 2 pink:

P(2 P) = 3/10

P(2 P) =30%

Tossing 1 blue and 1 pink:

P(B and P) = 6/10

P(B and P)=60% or 3/5

Not tossing all pink:

P(not all P) = (10 - 3)/10

P(not all P)= 7/10

P(not all P)=70%

Therefore the experimental probability of the event are: 3/10; 3/5; 7/10.
