To determine the probability of picking a yellow counter based on Joanne's experience of drawing from the bag, we can use the formula for probability:
\[
\text{Probability of an event} = \frac{\text{Number of successful outcomes}}{\text{Total number of possible outcomes}}
\]
In this case:
- The number of successful outcomes (the times she picked a yellow counter) = 7
- The total number of possible outcomes (the total number of draws) = 10
So the probability \( P \) of picking a yellow counter is:
\[
P(\text{yellow}) = \frac{7}{10}
\]
Thus, the probability of picking a yellow counter is \( \frac{7}{10} \) or 0.7.
\[
\text{Probability of an event} = \frac{\text{Number of successful outcomes}}{\text{Total number of possible outcomes}}
\]
In this case:
- The number of successful outcomes (the times she picked a yellow counter) = 7
- The total number of possible outcomes (the total number of draws) = 10
So the probability \( P \) of picking a yellow counter is:
\[
P(\text{yellow}) = \frac{7}{10}

Thus, the probability of picking a yellow counter is \( \frac{7}{10} \) or 0.7.
