The experimental probability that the next marble will be red is [tex]\frac{3}{20}[/tex]
The chance that something will happen, or how likely it is that an event will occur.
[tex]P(A) = \frac{number of favorable outcomes}{total number of outcomes}[/tex]
Where,
P(A) is the probability of an event.
According to the given question
number of times red marbles are drawn = 3
⇒ number of favorable outcomes = 3
Total number of trials = 20
⇒ total number of outcomes = 20
therefore,
the experimental probability of next marble being red is given by
[tex]P(red) = \frac{n(red)}{Trials}[/tex]
⇒ [tex]P(red)=\frac{3}{20}[/tex]
Hence, the experimental probability of next marble will be red is [tex]\frac{3}{20}[/tex].
