**1. Two dice are rolled. The events 'obtaining a six with the first die' and 'obtaining an even number with the second die' are independent. True or False?****2. A box contains 7 red balls and 4 white balls. Two balls are taken out and not replaced. The events 'the first ball is red' and 'the second ball is white' are independent. True or False?****3. A bag contains 3 green counters and 6 black counters. A counter is taken from the bag, its colour noted, and then replaced. A second counter is then taken from the bag. The events 'the first counter is green' and 'the second counter is black' are independent. True or False?**

A bag contains 2 red beads and 3 black beads. Two beads are taken from the bag without replacement.

Please enter your answer as a decimal as illustrated in the diagram.
