From the information given;
P(cold) = 0.4
P(no cold) = 1-0.4 = 0.6
The number of ways of selecting 4 from 10 = 10C4 = 210
Probability that the 4 selected with catch a cold:
P(4 will catch cold) = (10C4)*P(cold)^4*P(no cold)^6 = 210*0.4^4*0.6^6 = 0.2508
Hello There!
6 = 6 12 18 24 30 36
5 = 5 10 15 20 25 30
3 = 3 6 9 12 15 18 21 24 27 30
It would be 30.
Hope This Helps You!
Good Luck :)
Answer: What information tell me and i will try to help you as soon as possible :)
Step-by-step explanation:
Answer:
the first question is x=68/3 in standard from it is 3x=68
the second question is x= - 11/10
Step-by-step explanation:
for the second question the negative is beside the fraction.
4b² + 8b + 3 = 0
4b² + 2b + 6b + 3 = 0
2b(2b + 1) + 3(2b + 1) = 0
(2b + 3)(2b + 1) = 0
b = -1/2 or b = -3/2
