These are two independent events so the probability of both events is just the product of the probability of each event. We have:
Pr ( first spin is on red ) = 8 / 10 = 4 / 5 and
Pr ( second spin is on the rest of the sections ) = 2 / 10 1 / 5 Thus we have
Pr ( first spin is on red and second spin is on the rest of the spinner = ( 4 / 5 ) x ( 1 / 5 ) = 4 / 25
To find how many miles per hour you need to divide 50 by 5 to get the number of miles per hour and do the same thing to the 2nd step and to find the difference you need to subtract the numbers. Hope it helps!!!
The form of quadratic representing the roots can be expressed as,
Where p and q are the roots of the equation.
The form which represents the zeroes of function h is,
Where 2 and -2 are the roots of the function h(x).
Thus, option (B) is correct.
B because 120+ 40x equals the subtopic of the route of
Answer:
O.186 or 18.6%
Step-by-step explanation:
Let s = event of schizophrenia
B = brain atrophy
From our question we have:
P(s) = probability of those suffering from schizophrenia = 1.5% = 0.015
P(B|S) = probability of brain atrophy = 30% = 0.30
P(S') = 1 - 0.015 = 0.985
P(B|S') = 2% = 0.02
Probability Hinckley suffered from schizophrenia
= P(S|B) = P(B|S)P(S)/P(B|S)P(S)+P(B|S')P(S')
= (0.30x0.015)/(0.30)*(0.015)+(0.02)(0.985)
= 0.0045/0.0045+0.0197
= 0.0045/0.0242
= 0.185950
This is approximately 0.186 or 18.6%
