There are 4 green counters 6 yellow counters and 2 red counters. Joan picks a random counter out of the bag is 10 times, and she got a yellow counter 7 time. What is the experimental probability of picking a yellow?
The experimental probability of picking a yellow counter can be calculated by dividing the number of times Joan picked a yellow counter by the total number of times she picked a counter. In this case, Joan picked a total of 10 counters and got a yellow counter 7 times.
Experimental probability of picking a yellow counter = Number of times Joan picked a yellow counter / Total number of times Joan picked a counter
Experimental probability of picking a yellow counter = 7 / 10
Experimental probability of picking a yellow counter = 0.7
Therefore, the experimental probability of picking a yellow counter is 0.7 or 70%.
