Answer:
1/8 ;
12 / 51
Step-by-step explanation:
To select any 5 numbers out of 40
Number of selection required / total numbers
Probability of winning = 5 /40 = 1/8
Total number of socks = 18
White, W = 8
Black, B = 6
Blue, C = 4
probability, without looking in the drawer, that you will first select and remove a black pair, then select either a blue or a white pair?
P(B) * [(P(C) + P(W)]
Probability = required outcome / Total possible outcomes
P(B) = 6 / 18 = 1/3
Without replacement :
P(W or C) = 8/17 + 4/17 = 12/17
Hence,
1/3 * 12/17
= 12 / 51
108+103+98+105+85+112+119+82+94+115+126+89 = 1236
1236÷12 =103
Answer: Binomial
Step-by-step explanation:
1 / 3
A binomial setting has a set number of trials, and the variable in question is the number of
successes that occur in those trials.
A geometric setting does not have a set number of trials, and the variable in question is the
number of trials it takes to get the first success.
In both settings, the trials are independent and the probability of success remains the same on
each trial.
2/3
In this game, the player rolls 7 dice, and F is the number of dice that show a 5. So the variable is
counting the number of successes
The rolls are independent, and the probability of getting a 5 is the same on each roll,
3/3
F is a binomial variable
Answer:
y + 7.8 = 25.2
y = 17.4
Step-by-step explanation:
y + 7.8 = 25.2
(now we solve the equation .... we substract 7.8 from each side of the equation )
y = 25.2 - 7.8
y = 17.4
Answer:
Step-by-step explanation:
If the variation is proportional dividing the y-value by the x-value will give the same result for all table entries. That quotient is the constant of variation (k).
Here 6.4/4 = 11.2/7 = 16/10 = 20.8/13 = 1.6
The value of y varies directly as x, and the constant of variation is 1.6. The equation is ...
y = 1.6x
