Answer 1

Do you feel overlooded Total yes male 235 307 542 female 216 27/ 547 total SI 578 1089 p( he or shee feels overloaded) and there 216 females are 235 males 1089. So out of total 511 overloaded are (from the probability ☺ - SU a0-4692 table 1089 and is 2 chosen Randomly a female she feels overloaded indicates that he out are 276 female with overloaded of total 1089 276 so probability -0.2534 1989 B is female or ?
