Probability At least One | Examination Questions | Dr. Ruchi Khandelwal.

Probability of at least one event: if we want to find out the probability of happening of at least one event out of many independent events, we first find the combined probability of not happening of all these events and then subtract the same from 1. This gives the probability of happening at least one. The individual probabilities of several independent events can be denoted by = p₁ x p₂ x p₃...............pո. ( Probability of not happening of the events)= [ (1 - p₁) x ( 1 - p₂) x (1-p₃)........................(1-pո)] Probability of happening at least one of the events = 1 - ( probability of not happening of the events) = 1- [ (1 - p₁) x ( 1 - p₂) x (1-p₃)........................(1-pո)] Follow us on Facebook 👉Rtutor hub Follow us on Twitter 👉@rtutorhubruchi Follow us on Instagram👉Dr_ruchi_khandelwal Open this link to join my WhatsApp Group👉https://chat.whatsapp.com/Cr4WSbDfh5z...
