Answer:
The probability of drawing a second red card, since the first card is red is 25/51
Step-by-step explanation:
The probability of drawing a second red card since the first Card is red is:
P (R2 | R1) = P (R2 and R1) / R1
So:
P (R2 | R1) = (25/102) / 1/2
P (R2 | R1) = 25/51
Therefore the correct option is option 2.
the probability of drawing a second red card, since the first card is red is 25/51
Step-by-step explanation:
Put the value of x = -6 to all expressions:

The correct value of ''n'' in this equation will be -9
- Step-by-step explanation:
In order to find the value of ''n'' in this equation of the first degree, just <u>isolate ''</u><u>n</u><u>''</u>, and divide the right side into the left side of the equation:




So we can conclude that the value of ''n'' in this equation will be -9
3k+10=2k-21
move 2k to the other side
sign changes from +2k to -2k
3k-2k+10=2k-2k-21( combine like terms)
3k-2k+10= -21
k+10=-21
move +10 to the other side
k+10-10= -21-10
k= -21-10
answer:
k= -31
