Two dice are rolled simultaneously. What is the probability that the sum of numbers on the dice is 9?
दो पासे एक साथ फेंके जाते हैं। पासों पर आने वाली संख्याओं का योग 9 होने की प्रायिकता क्या है?
Given $P(A) = p_1$, $P(B) = p_2$, and $P(A \cap B) = p_3$. Then $P(A' \cap B')$ will be:
यदि $P(A) = p_1$, $P(B) = p_2$, और $P(A \cap B) = p_3$ दिया गया है, तो $P(A' \cap B')$ का मान क्या होगा?
If $P(A \cup B) = 5/6$, $P(A \cap B) = 1/3$ and $P(\overline{B}) = 1/2$, then the events $A$ and $B$ are:
यदि $P(A \cup B) = 5/6$, $P(A \cap B) = 1/3$ और $P(\overline{B}) = 1/2$ हो, तो घटनाएं $A$ और $B$ हैं:
If $P(A) = 0.25$, $P(B) = 0.50$ and $P(A \cap B) = 0.14$, then the probability that neither $A$ nor $B$ occurs is:
यदि $P(A) = 0.25$, $P(B) = 0.50$ और $P(A \cap B) = 0.14$ हो, तो न तो $A$ और न ही $B$ के घटित होने की प्रायिकता है:
