If two events are dependent on each other you have to multiply the probability of the first event times the probability of the second event.
first count all the marbles here there are 21
you are asked about picking two green marbles there are 7 out of the 21 total.
The first event would be 7/21
The second event would be 6/20 (since you didn't replace and you took out a green one)
now multiply your two fractions together:
and you get 1/10.
Answer:
its in order from 2 to 3
Step-by-step explanation:
Answer:
The pattern is that they are multiplying by -3 every time. 81*-3 = -243
I am pretty sure that it would be 13m + 8. All you have to do is combine the like terms.
Answer is B Mr James
Lets convert all the fractions, percentages to decimals:_
Mr James: 5/8 = 0.625
Miss Smith: 0.61
Mrs Lawson: 9/16 = 0.5625
Mr Tosh: 0.58
Mrs Cagle 0.53
So Mr James corrected the most homework.
