Question

you plant 30 african violet seeds and 9 of them sprout use experimental probability to predict how many will sprout if you plant 20 seeds

Answer 1

Given that out of 30 planted seeds only 9 of the m sprouted, then:
Experimental probability =(number of occurrence of event)/(total number of trials made)
=9/30
=3/10
thus the number of seeds that will sprout given that 20 seeds we planted will be:
3/10×20
=6 seeds

Answer 2

6 seeds are required that will sprout if you plant 20 seeds.

What is the probability?

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

P(E) = Number of favorable outcomes / total number of outcomes

It is given that out of 30 planted seeds only 9 of them sprouted, then

Experimental probability =(number of occurrences of the event)/(total number of trials made)

=9/30

=3/10

thus the number of seeds that will sprout given the 20 seeds we planted will be

3/10×20

=6 seeds

Therefore, 6 seeds are required that will sprout if you plant 20 seeds.
