Answer:
Step-by-step explanation:
3 envelopes having 2 red card
2 envelopes having 1 red card and 1 black card
1 envelope having 2 black cards
We are given that . An envelope is selected at random and a card is withdrawn and found to be red.
So, No. of ways of envelope having red card = 3+2 = 5
No. of required ways of envelope having 1 red card and 1 black card = 2
So, probability of getting an envelope having 1 red card and 1 black card =
Hence The chance the other card is black is
Answer:
Option A is the correct one.
Step-by-step explanation:
If f(x) = x² then g(x) = f(4x) = (4x)² = 16x² ........ (1)
Now, for any real value of x, the g(x) is positive.
Therefore, option B and option C is not correct.
Now, from the graph given in option A, it is clear that for y = 5, x value is near ±
.
So, putting x = in the equation (1), we get g(x) = 16(0.5)² = 4 which is close to 5.
Therefore, option A is the correct one. (Answer)
The chance of having a girl is 50%. Having two other girls doesn't change the odds. However, having three girls in a row is a 12.5% chance.
Answer:
x(x^2 + 6)
Step-by-step explanation:
We are to simplify -3x(x-4)-2x(x+3). Begin by performing the indicated multiplication. We get -3x^2 + 12x - 2x^2 - 6x.
Combining like terms, we get -5x^2 + 6x, which is equivalent to
x(x^2 + 6)
