Use the formula for the probability of the complement of an event. A coin is flipped 4 times. What is the probability of getting

raketka [301]

Answer: 15/16

Step-by-step explanation:

There will be 16 outcomes for 4 coins=2^4

Probability of only head is : P(C)=1/16

P(C) + P(C') = 1

P(C') = 1 - P(C)

P(C') = 1 - 1/16

Take the l.c.m

P(C') = (16-1) / 16

P(C') = 15/16

So the probability of getting at least 1 tail is 15/16

What’s the x and y intercepts of this equation: -3x-7y=84

Arlecino [84]

Answer:

The X and Y intercepts to the equation -3x - 7y = 84 is

x-intercept (s): (−28,0)

y-intercept (s): (0,−12)

Step-by-step explanation:

To find the x-intercept(s), substitute in 0 for y and solve for x

−3x−7⋅0=84

Solve the equation.

x=−28

x-intercept(s) in point form.

x-intercept (s): (−28,0)

To find the y-intercept(s), substitute in 0 for x and solve for y .

−3⋅0−7y=84

Solve the equation.

y=−12

y-intercept(s) in point form.

y-intercept (s): (0,−12)

Hope this helps.
