What does A106 14K P mean on gold ring?
Plumb.. TRUE GOLD
What does this stand for WPB?
W - stands for Weldable P - stands for made from Pipe B - stands for Grade B
Calculate the number p and q?
p/q form of the number is 0.3 is: (A) (B)
Throw a dice and toss a coin what is the probability that a number less than 3 and a tail result?
p(a) = 1/3, p(b) = 1/2, p(a and b) = p(a)*p(b) = 1/6
If two events are mutually exclusive and collectively exhaustive what is the probability that one or the other occurs?
If A and B are mutually exclusive, P(A or B)=P(A) + P(B) They both cannot occur together. For example: A die is rolled. A = an odd number; B= number is divisible by 2. P(A or B) = 1/3 + 1/3 = 2/3
If A and B are independent events then are A and B' independent?
if P(A)>0 then P(B'|A)=1-P(B|A) so P(A intersect B')=P(A)P(B'|A)=P(A)[1-P(B|A)] =P(A)[1-P(B)] =P(A)P(B') the definition of independent events is if P(A intersect B')=P(A)P(B') that is the proof
What is the product rule and the sum rule of probability?
Sum Rule: P(A) = \sum_{B} P(A,B) Product Rule: P(A , B) = P(A) P(B|A) or P(A, B)=P(B) P(A|B) [P(A|B) means probability of A given that B has occurred] P(A, B) = P(A) P(B) , if A and B are independent events.
What is the reciprocal of a positive rational number?
It is another positive rational number. The reciprocal of p/q is q/p.
What is the formula for inclusive events?
The probability of inclusive events A or B occurring is given by P(A or B) = P(A) + P(B) - P(A and B), where P(A) and P(B) represent the probabilities of events A and B occurring, respectively.
What is a P grade gcse?
A 'P' grade is most likely 'passing'.
How do you find P A given B?
P(A|B)= P(A n B) / P(B) P(A n B) = probability of both A and B happening to check for independence you see if P(A|B) = P(B)
Addition rule for probability of events A and B?
If they're disjoint events: P(A and B) = P(A) + P(B) Generally: P(A and B) = P(A) + P(B) - P(A|B)
