First you have to add 94 +94 and then 5+5 and then you add both totals and your answer is 190.
Answer:
45
Step-by-step explanation:
Answer:
The variable that is being predicted is the <u>dependent variable</u>.
Step-by-step explanation:
The regression analysis is used to determine the effect on the response or dependent variable with every one unit change in the predictor or independent variable.
In case of simple linear regression there is only one independent variable and in cases of multiple linear regression there are more than one independent variables.
The general form of simple linear regression is:
The general form of multiple linear regression is:
The dependent variable are usually denoted by the letter "<em>y</em>" and the independent variables are usually denoted by the letter "<em>x</em>".
Thus, the variable that is being predicted is the <u>dependent variable</u>.
Normally when dealing with coins the probability of getting heads or tails is 0.5 each. However in this case since its an unfair coin, the probability of getting heads is 0.2.
H - head
T - tails
R - red marble
pr (H) = 0.2
urn
6 red and 4 blue
pr (T) = 0.8
urn
3 red and 5 blue
when heads is obtained
red - 6/10 -0.6
blue - 4/10 - 0.4
therefore when multiplying with 0.2 probability of getting heads
pr (R ∩ H) red - 0.6*0.2 = 0.12
when tails is obtained
red - 3/8 - 0.375
blue - 5/8 - 0.625
when multiplying with 0.8 probability of getting tails
pr (R ∩ T) red - 0.375 * 0.8 = 0.3
using bayes rule the answer can be found out,
the following equation is used;
pr (H | R) = pr (R ∩ H) / {pr (R ∩ H) + pr (R ∩ T)}
= 0.12 / (0.12 + 0.3)
= 0.12 / 0.42
= 0.286
the final answer is 0.286
