Answer:
The probability of picking two consecutive purple marbles without replacement is 14.72%.
Step-by-step explanation:
Initially, there are 4+6+2+8 = 20 total marbles.
The probability of picking a purble marble is
P_{1} = \frac{number of purple marbles}{number of total marbles}
P_{1}= \frac{8}{20} = 0.4
Since there are no replacements, there are now 19 total marbles, 7 of which are purple. So, the probability of picking another purple marble is
P_{2} = \frac{7}{19} = 0.368
The probability P of picking a purble marble(P_{1}), not replacing it, and then picking another purple marble(P_{2}) is:
P = P_{1}*P_{2} = 0.4*0.368 = 0.1472 = 14.72%
Answer:
Step 2
Step-by-step explanation:
The answer should be 15x^2-3x^2y^2+y^4+3y
Step-by-step explanation:
4x - 12 < 16 + 8x
Bringing like terms on one side
-12 - 16 < 8x - 4x
-28 < 4x
-28/4 < x
-7 < x
Answer : number 3 is the inconsistent system
Explanation:
Look at the system for number 3
The slope is the same but the y intercept is not meaning that there is so solution. Which mean it’s inconsistent
Answer:
3/20
Step-by-step explanation:
Number of American Men: (2/3)(3/8) = 1/4
Number of American Women: 1 - (3/5) - (1/4) = 3/20 of the members are American women.
