Final Answer:
The probability of drawing a red or yellow ball from the jar is 16 / 25, rounded to four decimal places.
Step-by-step explanation:
To find the probability of drawing a red or yellow ball, first, calculate the total number of red and yellow balls in the jar. There are 7 red balls and 9 yellow balls, totaling 16 balls. The total number of balls in the jar is 7 (red) + 9 (white) + 9 (yellow) = 25 balls. To find the probability, divide the number of favorable outcomes (red or yellow balls) by the total number of possible outcomes.
The probability of drawing a red or yellow ball is calculated as 16 / 25. This is because out of the 25 balls in total, 16 are either red or yellow. By simplifying the fraction, the probability is 16 / 25 , which is equivalent to 0.64 when rounded to four decimal places. Therefore, the likelihood of picking either a red or yellow ball from the jar is 0.64 or 64%.
This probability represents the chances of selecting a red or yellow ball on a single draw from the jar. It signifies the ratio of the desired outcomes (red or yellow balls) to the total possible outcomes. Thus, when randomly selecting one ball from the jar, there's a 64% probability of getting either a red or yellow ball.
