What is the probability of getting two consecutive tails ?Consider another example where a pack contains 4 blue, 2 red and 3 black pens. If a pen is drawn at random from the pack, replaced and the process repeated 2 more times, What is the probability of drawing 2 blue pens and 1 black pen?A pack contains 4 blue, 2 red and 3 black pens. If 2 pens are drawn at random from the pack, NOT replaced and then another pen is drawn.

What is the probability of a student studying science given he/she is already studying maths?A single coin is tossed 5 times. What is the probability of getting at least one head?When two dice are rolled, find the probability of getting a greater number on the first die than the one on the second, given that the sum should equal 8.An urn B1 contains 2 white and 3 black balls and another urn B2 contains 3 white and 4 black balls. One urn is selected at random and a ball is drawn from it. If the ball drawn is found black, find the probability that the urn chosen was B1.ලගදි සා/පෙ,  උ/පෙ කරපු කෙනෙක් වෙතොත් මේ ටික කටුවට හදල එවන්නකෝ... ප්ලීස්<img src="/styles/default/xenforo/smilies/default/yes.gif"  class="smilie" loading="lazy" alt=":yes:" title="Yes    :yes:" data-shortname=":yes:" /><img src="/styles/default/xenforo/smilies/default/sorry.gif"  class="smilie" loading="lazy" alt=":sorry:" title="Sorry    :sorry:" data-shortname=":sorry:" /></blockquote>
