Answer:
There are 26 purple marbles in the bag.
Step-by-step explanation:
Firstly, you have to make an expression in terms of x where x represent red marbles. Given that the question says purple marbles is 2 more than 3 times the number of red marbles. So the expression is :
Let red marbles = x,
Next, given that the total marbles in the bag is 34 so you have to add both marbles together and solve the value of x :
Lastly, you have to substitute the value of x into the expression of purple marbles :
Let x = 8,
Answer:
0.0791
Step-by-step explanation:
Given that the probability of white eyes is 1/4 and the probability of red eyes is 3/4, for an individual fly.
Observations are independent
Let A be finding the white eyed fly and B
finding the red eyed fly
P(A) for any random trial= 0.25 and
P(B) = 0.75
Each trial is independent of the other
The probability that at least four flies have to be checked for eye color to observe a white-eyed fly
=Probability for I, II, III and Iv flies to have red eyes * Prob for 5th fly to have white eye
=
