This problem is easier solved by finding the probability that she does NOT do her homework both Monday and Tuesday, which is obtained by the multiplication rule.

P(no HW on Monday) = 1-0.75 = 0.25
P(no HW on Tuesday) = 1-0.75 = 0.25
P(no HW on both Monday and Tuesday) = 0.25*0.25=0.0625 
    [by the multiplication rule]

This means that the rest of the time (1-0.0625=0.9375) Elsie does her homework either Monday, or Tuesday, or both days.
=>
P(HW either Monday, Tuesday, or both) = 0.9375

(note: in current English, Monday or Tuesday means "either Monday, Tuesday, or both days")

Answer:

1.5

Step-by-step explanation:

Thinking process:

The probability of two events, A or B is given by the formula:

P (A or B) = P (A) + P (B)

The probability of doing homework on a Monday = 75 % = 0.75

Similarly,the probability of doing homework on a Monday = 0.75

Therefore, the probability of doing homework on Monday or Tuesday is given by:

P (M or T)  = P (M) + P (T)\\                  = 0.75 + 0.75\\                  =1.5

What is the equation of the line in slope-intercept form with slope -3/2 and y-intercept -5?
V125BC [204]

About Slope Intercept Form:

  • y = mx + b
  • m represents the slope
  • b represents the y-intercept or AKA the starting point

ABOUT PROBLEM:

  • Since -3/2 is the slope, it represents m in Slope Intercept Form
  • Since -5 is the y-intercept, it represents b in Slope Intrecept Form

y = mx + b

y = -3/2x + -5 --- IN Slope Intercept Form


Hope this helps you!!! :)
