Your Progress 0 / 25 attempted
Q 01 / 25
The probability of any event always lies between 0 and 1 (inclusive).
Q 02 / 25
The probability of a sure event is equal to 0.
Q 03 / 25
If an experiment has 10 equally likely outcomes, the probability of any one outcome is \(\frac{1}{10}\).
Q 04 / 25
If \(P(A)=0\), then \(A\) is an impossible event.
Q 05 / 25
If \(P(A)=1\), then \(A\) must occur.
Q 06 / 25
The probability of the sample space is always equal to 1.
Q 07 / 25
If two events are complementary, their probabilities add up to 2.
Q 08 / 25
If \(A\) and \(B\) are mutually exclusive, then \(P(A\cap B)=0\).
Q 09 / 25
For any event \(A\), \(P(A')=1-P(A)\).
Q 10 / 25
If outcomes are equally likely, classical probability can be applied.
Q 11 / 25
If \(P(A)=0.3\), then \(P(A')=0.7\).
Q 12 / 25
If two events are independent, then \(P(A\cap B)=P(A)+P(B)\).
Q 13 / 25
The probability of at least one event occurring is always greater than or equal to the probability of each event.
Q 14 / 25
If \(A\subset B\), then \(P(A)\le P(B)\).
Q 15 / 25
If \(P(A)=0.4\) and \(P(B)=0.5\), then \(P(A\cup B)=0.9\).
Q 16 / 25
If \(A\) and \(B\) are mutually exclusive, then they are also independent.
Q 17 / 25
If \(P(A|B)=P(A)\), then \(A\) and \(B\) are independent.
Q 18 / 25
For any two events, \(P(A\cup B)=P(A)+P(B)-P(A\cap B)\).
Q 19 / 25
If \(P(A)=0.6\), then \(P(A\cap A)=0.36\).
Q 20 / 25
If events are independent, occurrence of one affects the probability of the other.
Q 21 / 25
If three fair coins are tossed, the probability of exactly two heads is \(\frac{3}{8}\).
Q 22 / 25
If \(P(A)=0.5\), then \(P(A|A)=0.5\).
Q 23 / 25
If \(A\) and \(B\) are independent, then \(A'\) and \(B'\) are also independent.
Q 24 / 25
If \(P(A)=0.7\) and \(P(B|A)=0.2\), then \(P(A\cap B)=0.14\).
Q 25 / 25
If \(A\) and \(B\) are independent with \(P(A)=P(B)=0.5\), then \(P(A\cup B)=0.75\).
