Answer:
3/4
Step-by-step explanation:
Given the following :
Number of boxes = 2
First box :
White balls = 3
Blue balls = 2
Second box:
White balls = 4
Blue balls = 1
What is the probability that Frida picked a ball from the first box if she has selected a blue ball?
Probability (P) = (required outcome / Total possible outcomes)
Probability of picking first box : P(F) = 1/2
Probability of not picking second box :P(S) 1/2
Probability of picking blue from first box : P(B | F) = 3/5
Probability of picking blue, but not from first box : P(Blue not from second box) P(B|S) = 1/5
probability that Frida picked a ball from the first box if she has selected a blue ball?
P(F) * P(B|F) ÷ (P(F) * P(B|F)) + (P(S) * P(B|S))
(1/2 * 3/5) ÷ ((1/2 *3/5) + (1/2 * 1/5)
3/10 ÷ (3/10 + 1/10)
3/10 ÷ 4/10
3/10 * 10/4
= 3/4
Answer:
Step-by-step explanation:
to find the "solution" to this system, set f=g.
then we get:
plugging in 3,-3 for x in both equations, we get:
(3,7),(-3,-7),(-3,-5)
4x + 32 = 6x - 8
4x - 6x = -8 - 32
-2x = -40
x = 20
answer x = 20
Answer:-8,0
Step-by-step explanation:
Answer: 91.6666666667 pero lo redondeadas y te da de resultado 92.0% de probabilidades que no caiga un 4
Step-by-step explanation:divide 100 entre 12 y el resultado lo multiplicas por 11. no es como se saca la respuesta normalmente pero es una opción
