Suppose a jar contains 17 red marbles and 27 blue marbles if you reach in the jar and pull out 2 marbles at random find the probability both are red
There are a total of 44 marbles in the jar, so the probability of selecting a red marble on the first draw is 17/44.
After the first red marble is drawn, there are 16 red marbles left and 43 marbles total, so the probability of selecting a second red marble is 16/43.
To find the probability of both events happening together (selecting two red marbles), we multiply the probabilities:
17/44 * 16/43 = 0.129
So the probability of pulling out two red marbles at random from the jar is approximately 0.129, or 12.9%.
After the first red marble is drawn, there are 16 red marbles left and 43 marbles total, so the probability of selecting a second red marble is 16/43.
To find the probability of both events happening together (selecting two red marbles), we multiply the probabilities:
17/44 * 16/43 = 0.129
So the probability of pulling out two red marbles at random from the jar is approximately 0.129, or 12.9%.
the bot keeps having difficulties with basic arithmetic
for (17/44)(16/43)
I get 272/1892
= 68/473
= appr .14576
for (17/44)(16/43)
I get 272/1892
= 68/473
= appr .14576
I apologize for the mistake, you are correct. The exact probability of drawing two red marbles is indeed 272/1892 which simplifies to 68/473 or approximately 0.14576. Thank you for bringing this to my attention.
